pillars. There is also a large i\ hasalis^ and some non-plumed 

 setae on the leg. 



Mesothorax and metathorax. We find v. dorsalis, v. suprastig- 

 malis and v. prostiymalis which are about equally large. The 

 last mentioned wart lies on the same height as the very high 

 placed V. poststigmalis on the abdominal segments. V. dorsolate- 

 ralis is wanting. 



Behind v. prostif/tnalis is a small tuberculum with three or four 

 setae. It lies therefore on the place of the wing-rudiment. Besides 

 we find in many individuals a tuberculum with one or two setae. 



V. bdsalis is large. On the leg occur some setae which are not 

 feathered. 



Abdomen 1, 2. V. dor.taJis is a little smaller than v. auhdor- 

 mlis^ V. Huprmfif/malis is large. Large and far projcfting is v. 

 jiosfsfu/nKdis which is partly continued under the stigma towards 

 the head. V. infrmtigmalis is situated lower than in most of tiie 

 other families of caterpillars. V. basalts and v. i^edalis on the 

 place where on the abdominal segments the leg is fixed. 



Segm. 3, 4, 5, 6=1, except that v. pedalis is absent. But on 

 the leg are one or two strong setae. 



„ 7, 8 = 1. 



„ 9. Very small v. dorsalis, very large v. siibdorsalis which 

 has far extended in the direction of the missing v. suprastigmalis, 

 this being perhaps united with it. For the rest as 3. Moreover 

 there is a rather large tuberculum under the anal flap. I con- 

 sider this to be v. infrastigmalis of segm. 10. 



Consequently the 10th segment is very much reduced. 



Instar //. Duration 30 days. Length 12 mm. 



The whole animal looks exactly as in instar /, but between 

 the tubercula a few setae (generally not plumed) are found. 



Prothorax. V. dorsalis is still larger than in instar I and v. 

 subdorsalis too has grown longer. Under it is a new verruca. 

 For the rest as in instar I. 



On the abdominal segments we see some small tubercula in 

 the neighbourhood of v. infrastigmalis. V. poststigmalis now grows
